Tartisan Nickel Corp. (CSE: TN,OTC:TTSRF) (OTCQX: TTSRF) (FSE: 8TA) (‘Tartisan’, or the ‘Company’) is pleased to provide an update of the Company’s flagship Kenbridge Nickel-Coppet-Cobalt Project. The drill program is designed to test the on strike and down dip potential for additional nickel sulphide mineralization to enhance the size and grade of the Kenbridge Deposit.

A total of 3,350m of drilling has been completed to date. The first 4 drill targets have been completed (drill holes KB26-207, KB-208, KB-209 and KB-210 outlined on Figure 1). Samples have been delivered to AGAT Labs in Thunder Bay for analysis. Assays are pending for hole KB26-210. The drill rig is currently drilling the 5th drill hole KB26-211. This hole is designed to be drilled below the existing shaft bottom to test for the depth extension to the deposit.

Reported in this release are the results from the 3rd infill drill hole KB26-209. Results from the hole confirm both A and B zones were intersected as outlined in the Table 1 below. Zone A was intersected from 823.6 to 825.0m drill depth and returned 0.31% Ni, 0.26% Cu over 1.4 metres. Zone B was intersected from 862.5m to 865.5m drill depth. Results were 2.17% Ni, 1.45% Cu over 3.0 metres. Drill core intersection widths are estimated to be between 65 and 80% true width.

Mark Appleby, CEO of Tartisan Nickel Corp stated, ‘We continue to see high grade intercepts from our Phase 1 drill program at the Kenbridge Nickel-Copper-Cobalt Project.’ ‘Intersecting 3 metres of 2.17% Ni and 1.24% Cu confirms continuity of significant nickel-copper mineralization in this part of the system. These previous results should strengthen our ability and confidence to potentially upgrade our resource and in the projects over all potential to deliver meaningful value for stakeholders.’

The technical information in this news release has been prepared in accordance with Canadian regulatory requirements as set out in NI 43-101 and reviewed and approved by Dean MacEachern, P. Geo., an Independent Consultant to the Company and a Qualified Person as defined by NI 43-101.

QA/QC

Sample QA/QC procedures for Tartisan have been designed to meet or exceed industry standards. Drill core is collected from the diamond drill and placed in sealed core trays for transport to on-site sampling and core cutting facilities. The core is logged and samples taken from 0.3m to a maximum sample length of 1.5m. The core samples are split with a diamond blade saw with continuous running water, half of the sample is sent for lab testing, and the remaining half core is left in the core box for record or further sampling. The core samples are bagged in heavy plastic bags with 6 samples being placed into a rice bag for transport to AGAT Laboratories in Thunder Bay, ON or Calgary, AB for assay. Samples are submitted in batches of 50. 100g blind certified reference materials (CRMs) from CDN Resources, as well as, duplicates and blank samples are systematically inserted by the Company into the sample stream with reference to the mineralization in the sampled rock and analyzed as part of the Company’s quality assurance/quality control protocol, as well, AGAT labs implements their own quality control testing by inserting their own CRMs and Blanks in the sample stream for accredited testing.

All drill core samples were prepped and analyzed at AGAT Laboratories in Thunder Bay, Ontario or shipped to Calgary for testing. An ISO/IEC 17025 2017 certified independent laboratory from organizations like the Standards Council of Canada (SCC), the Canadian Association for Laboratory Accreditation (CALA), ANSI National Accreditation Board (ANAB) and the American Association of Laboratory Accreditation (A2LA). They maintain accreditations across their facilities in Alberta, Saskatchewan, Ontario, Nova Scotia, Newfoundland, Quebec and internationally.

NQ-diameter sawed half-core samples from the drilling program were securely sent by Tartisan Nickel Corp’s geologists to AGAT Laboratories Ltd. (AGAT), with sample preparation in Thunder Bay, Ontario, and analysis in Thunder Bay, Ontario & Calgary, Alberta. Samples were processed for Au, Pt and Pd analysis by 50-gram fire assay with ICP-OES finish and for four acid digestion, multi-element analysis by inductively coupled plasma & mass spectrometry (ICP OES + MS). AGAT sample preparation and laboratory analysis procedures conform to requirements of ISO/IEC Standard 17025 guidelines and meet the requirements under NI 43-101 and CIM best practice guidelines. AGAT Laboratories is independent of Tartisan Nickel Corp.

Samples were dried and crushed to 2 mm, from which a 250 g sub-sample split was then pulverized to 85% passing a 75 micron sieve. Following preparation, assays were determined by the ICP OES method. A 0.25 g aliquot of the prepared pulp was digested in a 4-acid solution consisting of hydrochloric, nitric, perchloric and hydrofluoric acids. 4-acid is a near total digest and only the most highly resistant minerals are not dissolved. The resulting solution was analyzed via ICP-MS and ICP-ES for 8 elements and was corrected for inter-element spectral interferences. Lower detection limits for this procedure are 0.01 ppm for nickel, 0.01 ppm for copper, 0.01 ppm for cobalt, 0.01 ppm for platinum, 0.01 ppm palladium, 0.01 ppm silver and 0.01 ppm for gold.

Samples with initial results beyond the upper detection limit of the ICP OES method were analyzed by (201-071) 4 acid digest – Metals Package, ICP-OES/ICP-MS finish (CGY). The thresholds are >1% for nickel, copper and cobalt. AGAT Laboratories employs internal quality control standards, duplicates and blank samples at set frequencies. Tartisan Nickel Corp. stores all its drilled core on-site and takes pride in its facilities and strives for excellence in its QA/QC procedures.

Additionally, Tartisan Nickel Corp. will be at PDAC 2026 March 1^st to 4^th 2026 hosting Booth 2633. We welcome everyone to come and learn more about Tartisan and our 2026 initiatives.

GRANDE PRAIRIE, ALBERTA (February 24, 2026) TheNewswire – Angkor Resources Corp. (TSXV: ANK,OTC:ANKOF) (‘ANGKOR’ OR ‘THE COMPANY’) announces the completion of a trenching and sampling program at the CZ Gold Prospect in Ratanakiri Province, Cambodia.

As previously announced (see Angkor Resources ADVANCES EXPLORATION ON CZ GOLD AND WILD BOAR PROSPECTS, ANDONG MEAS LICENSE, CAMBODIA), the Company’s mineral exploration team initiated a large-scale trenching program at the CZ Gold Prospect, located on the west side of the Canada Wall prospect. The program is designed to determine the geology, structure and orientation of the quartz stockwork zone and its wall rocks, and to collect representative samples for analysis.

The trenching program consisted of twelve trenches excavated across the CZ Gold Prospect area. Each trench measured approximately five meters in length, two meters in width, and five meters in depth. Due to the steep slope and required depth of the trenches, the Company made the decision to utilize excavation equipment to safely and efficiently complete the program.

Figure 1: The slope and depth of the trenches contributed to the decision of using equipment for the excavation program at the CZ Gold Prospect.

The excavation process involves digging each trench to the target depth, at which point Angkor’s field team entered the trench to collect samples directly from the exposed geology, including veining and stockwork visible in the trench walls. Once sampling was complete, the team exited the trench and all samples are marked, bagged, and prepared for testing and analysis on the surface. As soon as sampling was finished at each location, the trenches were filled in and the site was restored.

Figure 2: Angkor staff sorting sample material and preparing samples for sieving, analysis, and testing,

The Company collected 298 samples of veins, side walls, and cross sections from the twelve trenches. Each sample will be split into three parts for different methods of analysis: one part for panning in the creek adjacent to the prospect, one part for portable X-ray fluorescence (XRF) analysis, and one part for fire assay. This multi-method approach is intended to provide a comprehensive geochemical characterization of the stockwork zone and to evaluate gold content across the target area.

The Company completed sampling this weekend and has started several weeks of analysis of the samples before interpretation of the data can be completed.

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

TORONTO, ON / ACCESS Newswire / February 24, 2026 / NextSource Materials Inc. (‘NextSource‘ or the ‘Company‘) (TSX:NEXT,OTC:NSRCF) is pleased to announce that it has closed its previously announced brokered private placement offering (the ‘Offering‘) of units of the Company (the ‘Units‘) for aggregate gross proceeds of C$24,999,987, issuing 58,823,500 Units at a price of $0.425 per Unit.

The Offering was oversubscribed due to strong investor demand, with investor allocation capped by the final amount of C$24,999,987. Vision Blue Resources Ltd. (‘Vision Blue‘) purchased 27,944,464 Units under the Offering to maintain its pro rata ownership in the Company.

The net proceeds from the Offering are expected to be used to advance the UAE Battery Anode Facility, update the Molo technical report and for general corporate purposes as disclosed in the offering document.

Each Warrant entitles the holder thereof to purchase one Common Share at an exercise price of C$0.55 per Common Share for a period beginning 61 days after the date hereof and expiring 36 months following the date hereof.

The Units distributed in connection with the Offering were issued and sold in accordance with the listed issuer financing exemption under Part 5A of National Instrument 45-106 – Prospectus Exemptions, as amended by Coordinated Blanket Order 45-935 – Exemptions from Certain Conditions of the Listed Issuer Financing Exemption (the ‘LIFE Exemption‘). A copy of the offering document related to the Offering is available to access under the Company’s issuer profile on SEDAR+ at www.sedarplus.ca and on the Company’s website at www.nextsourcematerials.com. In accordance with the LIFE Exemption, the Units issued in connection with the Offering are not subject to a hold period pursuant to applicable Canadian securities laws. The Offering is subject to final approval of the Toronto Stock Exchange.

The Offering was conducted on a ‘best-efforts’ basis by Stifel Canada, acting as lead agent and sole bookrunner, and Maxim Group LLC, as co-agent (the ‘Agents‘).

The participation of Vision Blue in the Offering constitutes a ‘related party transaction’ pursuant to Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (‘MI 61-101‘). The Company has determined that the transaction is exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 by virtue of the exemptions contained in Sections 5.5(a) and 5.7(1)(a) of MI 61-101, as neither the fair market value of securities issued to Vision Blue nor the consideration paid by Vision Blue exceeded 25 percent of the Company’s market capitalization. The Company did not file a material change report in respect of the transaction 21 days in advance of closing of the Offering because Vision Blue’s participation had not been confirmed. The shorter period was necessary in order to permit the Company to close the Offering in a timeframe consistent with usual market practice for transactions of this nature.

Alto Ruri Gold Project: High Sulfidation Epithermal System in Peru

The Alto Ruri Gold Project is located approximately 15 kilometres south of Barrick Gold’s Pierina Mine, which is currently in its closure and reclamation phase following more than two decades of production.

Pierina demonstrated the presence of a robust high-sulfidation epithermal gold system within Peru’s Cordillera Negra belt. Alto Ruri shares similar geological characteristics, including vuggy silica and advanced argillic alteration, supporting the potential for a preserved epithermal system within the same regional corridor.

The Alto Ruri Gold Project comprises approximately 4,700 hectares of wholly owned mineral concessions situated within Peru’s prolific Miocene Tertiary Volcanic Arc, host to multiple world-class gold and copper deposits.

Initial drilling by Compañía de Minas Buenaventura in 1997 included 12 shallow drill holes totaling 2,254.5 metres. (Refer to the Company’s news release – March 4th, 2024).

The most significant intercept from Hole 001-97 returned

• 131 metres grading 2.55 g/t gold from surface, including
• 54 metres grading 5.39 g/t gold

These results were re-assayed in 2011, confirming the presence of a well-developed high-sulfidation epithermal system associated with vuggy silica and advanced argillic alteration.

True widths remain undetermined, and modern confirmation drilling is planned as part of the Company’s systematic advancement strategy.

The Alto Ruri Gold Project represents a modern re-evaluation opportunity within a proven Andean gold district that has not undergone comprehensive exploration in nearly three decades.

Stallion Uranium Corp. (the ‘Company’ or ‘Stallion’) (TSX-V: STUD; OTCQB: STLNF; FSE: FE0) is pleased to announce the completion of an extension to its previous ground gravity survey along the Coyote Corridor, located within the Southwestern Athabasca Basin Joint Venture (‘JV’) Project in partnership with Atha Energy Corp. (TSX-V: SASK).

The recently completed program represents a direct extension of the Company’s original gravity grid and was designed to expand coverage over gravity responses observed along the margins of the initial survey area. The objective of the extension was to determine whether these edge anomalies form part of a larger, continuous gravity feature associated with the interpreted structural corridor at Coyote.

Data from the expanded survey is currently undergoing processing, quality control, and preliminary modelling. The Company will provide results once interpretation has been completed.

Highlights:

• Significant gravity low anomaly identified, closely resembling the geophysical signatures of NexGen Energy’s Arrow Deposit and other significant discoveries in the Athabasca Basin
• Structural and geophysical features align with those of the Arrow Deposit and PCE discovery, reinforcing the potential for Tier-1 uranium mineralization
• Gravity anomaly located in a structurally complex corridor, characterized by intersecting conductors and breaks, which are prime settings for uranium deposition
• Ongoing 3D Inversion of Ground Gravity to identify depth and shape of the gravity anomaly

‘The completion of this gravity extension is an important step in systematically advancing the Coyote Target,’ said Matthew Schwab, CEO of Stallion Uranium. ‘Expanding the grid ensures we fully evaluate gravity responses identified at the edges of the initial survey and maintain a disciplined, data-driven approach to exploration.’

Darren Slugoski, Vice President Exploration, added,

‘This extension allows us to properly assess the continuity of gravity features along the structural corridor before finalizing drill targeting. With data processing underway and a potential eastern grid about to commence, we continue to build a comprehensive geophysical dataset across the broader Coyote trend.’

Survey Extension Overview:

The gravity survey extension increases overall coverage across the Coyote structural corridor and enhances density control along strike and across interpreted conductive breaks. The combined original and extended grid now provides improved resolution of subsurface density variations that may be associated with alteration and basement structural complexity.

Gravity surveys are a key component of Stallion’s integrated exploration approach, as gravity lows within the Athabasca Basin are commonly associated with hydrothermal alteration systems developed along graphitic basement structures.

The survey encompassed a total area of 2,097 hectares, with 2,226 gravity stations strategically placed to detect subsurface variations in density that may indicate uranium alteration. The results revealed a substantial gravity low anomaly, a hallmark feature associated with large-scale uranium deposits, such as NexGen Energy’s Arrow Deposit. The Arrow Deposit, one of the most significant uranium discoveries in the Athabasca Basin, shares multiple geological and geophysical similarities with the Coyote Target, strengthening confidence in the potential for a high-grade uranium discovery.

About the Ground Gravity Survey:

Concluding February 10, 2026, MWH Geo-Surveys (Canada) Ltd. carried out a gravity survey at the Coyote Target in Saskatchewan. The survey utilized a customized L&R digital, electronic feedback gravity meter, operated via proprietary controller software. These advanced gravity meters, incorporating electronic levels and electronic nulling, ensure fast, accurate, and reliable readings, particularly in cold-weather conditions.

At each gravity station, GControl software, developed by MWH Geo-Surveys, recorded gravity samples at 1-second intervals. The resultant average of these readings was used as the final gravity measurement, significantly reducing high-frequency noise caused by wind and ground motion. Additionally, GControl calculated real-time, location-specific tidal corrections during data collection, enhancing the accuracy and reliability of the survey results.

With a typical mean data accuracy of 0.02 mgals, MWH Geo-Surveys continues to set the standard for high-resolution gravity surveys, delivering reliable results for resource exploration and geophysical studies.
